Re: partial download of modis and viirs data

Hello, I am not sure which MODIS and VIIRS products you are interested in, but most of our MODIS/VIIRS land products are available through our AppEEARS site: https://appeears.earthdatacloud.nasa.gov/ AppEEARS will spatially and spectrally subset and it can reformat and reproject also. It outputs a ....

Re: Harmonization or fusion of Landsat and Sentinel-2 data for geomorphological analysis of Italian rivers

Thanks Rosita for the follow up.
I will see if our science folks have any suggestions. Also, hopefully someone from the generally science community that has some thoughts on this will chime in. I will let you know what I hear. Have a good weekend.

Re: how can i get or produce the MCD43A4 8days?

Good Morning, The temporal frequency of the MCD43 products can be a little confusing. They are a 16-day product that is produced daily. The day given in the individual granule IDs are actually the 9th day of the 16-day period. So, for instance, please see the 2 examples below: MCD43A4.A2024315.h11v0...

Re: how can i get or produce the MCD43A4 8days?

Hello, I would just like to verify, are you looking for a product like the MCD43A4 which is produced daily and uses 16 days, only it would be an 8-day instead of 16-day? Or is this a GEE question asking if it is capable of doing that? GEE is not a NASA site, so we are not sure about what all it does...

Re: Harmonization or fusion of Landsat and Sentinel-2 data for geomorphological analysis of Italian rivers

Hello,
I will ask some science folks there thought on this. So, just to make sure, do you want something like our HLS data, only rather then 2-3 days apart it is several years: https://doi.org/10.5067/HLS/HLSL30.002
Thanks,

Re: Missing data in MODIS/Terra+Aqua AOD and Water Vapor from MAIAC, Daily L3 Global 0.05Deg CMG V061

Hello, Could you give us more specifics on the area that is missing data. If it is over deep ocean, that is expected. Please see page 6 of the User Guide for more information on this: https://lpdaac.usgs.gov/documents/1500/MCD19_User_Guide_V61.pdf If it is over land can you give us a coordinate rang...

Hi Brayan, I see there are about 8,712 files to download, I wonder if the browser is limiting the download size? Can you try a different option, wget seems to work well: https://github.com/nasa/LPDAAC-Data-Resources/blob/main/guides/bulk_download_using_wget.md Possibly a different browser might work...
